Abstract
A detailed analysis is conducted on the sources of Beauty mesons (B mesons) through the strong decay of η_b (5S), which represents one of the singlet-spin states S-wave bb ̅ bottomonium mesons. That is considered a significant step in understanding the physics behind the strong decay of bottomonium mesons, which is demonstrated to furnish us with a plentiful source of Beauty mesons. Their rare decay is regarded as a gateway to a new realm of physics, commonly called New Physics or Beyond Standard Model. The expected masses for higher bottomonium mesons are determined within the framework of the nonrelativistic quark model, and the recently obtained experimental data exhibit substantial concordance with our findings. Additionally, other theoretical forecasts align with our outcomes. The Quark Pair Creation model is employed to compute the strong decay of the η_b (5S) meson. Moreover, the strong decay branching ratio is determined. Novel findings regarding the partial strong decay widths of the η_b (5S) are obtained, while the total decay width aligns with previous studies. The strong decay width of the B^* B^* mesonic pairs channel is expected to be the greatest width by the ratio (∼ 56.37 %) concerning the higher scalar η_b (5S) state. additionally, the B_s^* B_s^* channel is predicted to have the next-to-dominant width relative to η_b (5S) state.
